[Q] Problem regarding super user and USB connection - Galaxy Note II Q&A, Help & Troubleshooting

Dear All,
I have encountered a problem with my note 2 that unfortunately closes a lot of doors for me to fix. I thought about asking you guys and hopefully this has not been asked before. Ok so my problem is that I had rooted phone ages ago and i had SuperSU installed with the root. Later on some official update came out and I let it update. After that I might have lost my root there and then not sure though. When I try to do something in root it won't let me, also it fails when trying to change super user app. What is killing me mostly is that any computer I connect using different cables, won't recognise my phone, as if it was not even connected although it charges normally. At first it was sometimes charging and not, sometimes freezing if connected to the USB. It might be hardware related but I want to try to fix this issue first to be sure. I can't even use Odin since it's not being detected so unrooting and going back to the seller is out of question.
Can anyone help me please? I am thinking of trying custom firmware through sdcard installation but i cant even install CWM and when using official recovery the package is not accepted. (signature issues). There may be some easy workaround I do not know of hence me asking you experienced guys.
Big thanks for reading this and hopefully helping me.

So you mean odin is not detecting phone in download mode ?
Try connecting the phone and see if adb works but I don't really think it would work. Try another cable. Could be that usb port is damaged.
Try another recovery.

No, Odin is not detecting the phone although it starts charging like normal. I will check adb later tonight when I am on my home pc. I have tried in total 4 different cables same result. I have used 3 different operating systems on different computers, still not detected. Usb port might be damaged but I don't think they will be happy seeing its rooted.(they being the store i bought it from, that is why I have not gone to them yet.

I have a similar issue since 4.1.2 however my phone is recognized by computer and odin in download mode, are you sure you tried it on download mode?

Yes I have tried download mode, that's why this problem is killing me :/ The root access is completely unusable and not working too.

[Q] Changing firmware without Odin or root access

Hi there,
I know it's a bit of a stretch but I don't know what to do at the moment.
My Note 2 is behaving strangely as it's not being detected by my pc, just charging. I have tried different PCs and cables with same result. Some time ago, when connecting the usb, it would hang or stop charging and the screen would not turn off when not used. I had rooted the phone and after the official update came out, I let the phone install it. Right now I do not have root access and when trying to update the binaries, it would not let me. I would have gone to the shop to check maybe the USB port is damaged but since it has 1 count on download mode and Super SU installed, i believe it's not covered by warranty.
I was looking to reinstall the official firmware untouched but I can't possibly do it as I cannot use Odin or CWM since its not rooted.
Can anyone help me?
Thanks
Install drivers.
If odin doesn't detect phone in download mode then it could be a hardware issue as well.

[Q] Unrooted GS3 with mobile odin. Broken now and can't fix

Long time listener first time caller (this is my first post here) I'm going to try not to leave out any details. Bear with me.
I rooted my Tmobile Galaxy s3 for the first time and installed CM10.1. It was great for a few months, then it started getting glitchy. So I would flash the nightly release and it would be fine for a while. I decided to unroot and start fresh. It was then that I discovered the PC wouldn't recognize the device. I followed a youtube tutorial to unroot with Mobile Odin. I extracted and flashed a stock image called Tmobile_GS3_SGH-T999_4.0.4 after clearing counter with Triangle Away.
Well it seemed to go well, unrooted my device, but now the OS is incomplete. No internet app, messaging won't work at all, and it keeps crashing and freezing. The usb port is still not working so I cannot root with my computer, and the flash counter still says 1 and status says modified.
Tmobile sent me a new one on warranty, but I'm really worried they're gonna charge me 500 bucks because it's "modified". I have a few days before I have to send it back, Is there anyway that I can fix this without connecting it to my computer? Any help is GREATLY appreciated.
Thanks

First thing to do is to put the phone into DOWNLOAD mode to TEST it and see if ODIN will recognize it.
If Odin recognizes it then there is NO need to send it back to Samsung, all it needs is a proper Odin flash.
Just because when all those missing apps and the usb had issues it does not necessarily mean that Odin will not recognize the phone.
If your computer is not working or you don't have a windows computer find a relative or a friend who has one.
Even a laptop computer would do just fine.
Good Luck!
Tried that
Thanks for your response, I have tried connecting it to Odin in download mode and it still will not see it. I really don't know what the problem could be. the usb used to work fine and there has been no physical damage.

Try a different usb cable and or plug usb into different port,
if that fails, re-install the Samsung usb drivers for the phone.
Remember, if the phone goes into download mode 99.999% of the time the phone
can be flashed successfully using Odin.
The main reasons for usb issues in "download mode" are either loose connection to computer's usb ports,
usb cable intermittant or the Samsung usb drivers in the computer are corrupted in one way or another.
Thanks again
I guess I should have put this in my first post. I have tried 2 different cables in every port on 2 different computers. I have re installed the drivers multiple times as well. Also the new phone they sent me is recognized just fine.

You are in a tough spot. I don't know if you have the stock recovery or not but if not you can either download the stock rom on the phone again...you know the best way although unethical really...being that the usb port is down is to re root it and flash a rom like the gt 1300 or whatever the international version is and intentionally hard brick your phone. Hard brick meaning won't even turn on withOut jtag and that even just clears everything out and reloads software like from the factory.If the phone won't boot up then there's no way for the person to tell its been modified. Majority of the time samsung doesn't get the damaged phones its some idiot making 8 bucks an hour to refurbish phones. That's what I would suggest you do being that the counter is still saying one flash
tmobile s3 running wicked. best rom i've ever used
Pretty sure I'm on stock recovery. it does give me an option to "apply update from external storage"
Thanks for all your help, I'll try to flash the stock rooted rom through the stock recovery although i'm not optimistic.
I will check out the wicked rom you mentioned, although I am a little hesitant to root my new one after this ordeal.
but how do I re root it if I have no usb or custom recovery?

If you can get your phone to boot normally with any stock rom rooting will not be a problem at all.
If you get the phone working and booting properly you would be very lucky but from reading
everything you have wrote so far I highly doubt that you can successfully flash any rom at all
unless you have forgotten to tell us something.
Don't worry about rooting, worry about getting the phone to boot and work properly with stock rom.
yep. running stock recovery. hopeless?

I never said a word about stock recovery, I said STOCK ROM.
Invest in a JIG, it puts your phone into download mode instantly even if you cannot
do it manually with the three buttons as long as the phone is not completely dead.
You can buy a jig for less than $4.00 shipped on eBay, it's great little tool.
All you do is remove the battery from the phone and put it back in then simply plug
the jig into the usb port then in a couple seconds it will be in download mode then you
can unplug the jig and the phone is ready to be odin flashed..
Remember what I said before, just because the usb did not work with some
rom you flashed it does not mean that it will not work for download mode.
The jig was one of the best investments I have made when I started using these samsung android phones.
Once in download mode it will allow you flash the stock or stock rooted Jellybean 4.1.1 rom.
This is my best advice.
I am not having a problem getting into download mode, I will take your advice and buy a jig though in case I ever need it. Again, thanks for all your help, I think I may have to send it back and hope for the best.

Before sending it back, if I were you I would find a friend or family member who has
a windows computer and just for the hell of it install the usb drivers in the computer
just to see for sure that while in download mode and connected usb cable if Odin still
is not lighting up the [COM:xx] top left rectangle on Odin screen.
I have odin flashed many phones dozens of times in the past 3 years and I have yet
to come accross one which goes into download mode but odin is not reconized
unless there is something wrong with the windows computer or usb ports and drivers.
That only happens as I said before, if there is something wrong with the drivers,
usb ports and or usb cables or some other malfunction in the windows computer.
Just think, if it works no need send the phone to samsung plus you would have learned
something too.
I did try my other computer with the same results, tomorrow I will try it with my girlfriends laptop, I am starting to think something happened to the usb jack. It didn't work before I unrooted it either, that's why I used Mobile Odin. I am all about learning this stuff though. I plan to root every new phone I get, this has just been a little frustrating.

This is the first I heard that the usb did not work before and the usb socket might be broke.!!!
In that case since you cannot use the Wifi in your phone to transfer and install apps since it cannot boot normally
(unless I am missing something again) and you cannot use usb and it would not even help to remove the external
sd and copy any apps at all since you would have no way to install the apps.
Then you are right, you have to send it back, exchange it and hopefully you can come up
with a good enough excuse why it's not working so samsung will not charge anything )which I doubt)
I must not have been clear, I can use the phone. it makes calls, the wifi works, i can use third party messaging and browser apps. again, there has been no physical damage. the socket worked a few weeks ago when I rooted it. I only noticed it not working when I went to unroot it.
So basically it sounds like there is no way to root or install custom recovery without usb, correct?

[Q] USB device not recognized, half rooted, no custom recovery--Totally messed up!

Here is my problem where I can't get my Sprint S3 connected to PC, I am half rooted, and have no custom recovery, I can't flash anything on my phone except OTAs, please help, any help is much much appreciated.
Background :
I had this phone working completely fine, I bought aftermarket USB cable and attached it to the PC, everything went smooth it got connected fine in MTP mode, on second day when I tried to connect it, it gave me error that USB Device Not Recognized.
Problem :
The phone is not getting connected to PC in any way, whether it is MTP, DM+Modem, PTP, ADB, etc... not even in download mode to flash it via Odin. No matter on which mode I am it always give me error that USB Device Not Recognized.
It sense when I change modes while it is connected to PC, like when I am on MTP and I click DM+Modem or I click USB Debugging, it displays that USB Device Not Recognized message again, so I it is sensing mode changes.
What I did so far :
Changed cable and used brand new Samsung Original cable, changed USB ports, changed 4-5 computers, installed and re-installed drivers numerous times, my friend who does the phone repairs changed Micro USB Slot on the phone 4 times with Original ones, he even took one from working phone and put in on this phone, no luck so far.
My inputs :
I've searched really a lot about this problem, but didn't find any single solution.
Some guys on forums reported that they solved problem by flashing a stock or custom rom as there might be a problem with Kernel.
I can't flash anything on my device since I am on stock recovery and half rooted, I had LJ7 rooted stock on my device, and I took MD4 OTA, now, my phone is half rooted, when I install any application which requires root, I get message that 'Superuser permission denied'.
I can't even uninstall Superuser, because it is system app, I tried to re-root phone via Motochopper method but it doesn't work.
I flashed this phone to different carrier, so, I am afraid I will loose my flash if I take latest 4.3 OTA.
PLEASE HELP IF YOU HAVE ANY SOLUTION FOR THIS PROBLEM, I WANT MY PHONE TO GET CONNECTED TO PC ANYHOW.
I AM READY TO DO ANYTHING YOU SUGGEST TO RECOVER MY PHONE.

[Q] Cannot Restore G3 To Stock Using Flash Tool

I tried to use a volume fix by changing the values in some system files on my rooted G3, rebooted and got stuck at the LG Bootlogo. Been trying lots of things, finally used this thread: http://forum.xda-developers.com/showthread.php?t=2799647 but the flash tool fails at 14 seconds saying failure to enter download mode. I have a D851C on T-Mobile, it is in download mode when I run the program and no change occurs on the screen save for the text log at the bottom. Upon booting into DL mode, it says USER B94. After unplugging and plugging it back in to start the unroot it changes to USER S0.0 AS0.0 B94 UHS then on the next line S U LG-D851 04.4.2 Hrev_10 and the next D85110c. It takes a good 50 seconds for the flash tool to change from saying awaiting connection, and then at 14 seconds it looks like the photo. The names of the dll and tot I am using are, respectively:
LGD851_20140611_LGFLASHv160
LGD851AT-01-V10c-310-260-JUN-20-2014+0
Yes I have set the port to 41 in device manager.
What the heck is wrong?
Someone please help I was supposed to fly out of state today but now I don't think I can without a phone and I can't afford a new one, I'm a student
Did you put your phone in download mode? It's not broken you just need to successfully flash it. It says download mode failed so here's a simple way to enable it if you ate having trouble. Pull out the battery then hold volume down and put it back it and plug in the cable. This should be done in a relatively fast manner to enable it if you are having issues getting into download mode.
Edit I know you said you put it in DL mode but I had a similar issue with my F400S so its worth a try.

PC Suite won't recognize it if you don't use the correct version. The latest from LG's site is in fact the wrong version. You need the version that's about 223mb in size. Sorry, I'm not sure of the version and am currently busy fixing my phone with it, so can't check. Perhaps someone would kindly supply you with a download link.

Did you try a different USB port on your computer? Drivers get honked up easily using flashing tools and sometimes using a different port, or even a different USB cable can fix your problem. More likely another usb port, but I've also had a bad cable as well.

That's the problem is the only cable that works is the one that came with it, and I've used 3 of my 4 on my laptop, so I doubt it's the port

Also you have to realize the phone doesn't turn on. I get the LG logo, download mode, or factory reset. That's it
If that is the only cable that works - my guess is there's something probably wrong with the micro usb jack on your phone.. it shouldn't be that finicky where only 1 of 4 cables would work. If you do a warranty return, you might get lucky anyways. Several folks have posted on XDA that the stores where they returned phones were either clueless or didn't care about the status of the root code. Of course, YMMV.

You misunderstand: The cable that comes with the G3 is the only one GUARANTEED to work with these operations. Has nothing to do with the jack. Getting a new one in the mail tomorrow, can't tell if it's rooted if they can't access the filesystem

[Q] USB not recognised

Can anyone help me please.....?
I recently updated my Note 4 to lollipop and since then my PC cannot recognise the phone.
I have tried a variety of USB cables.
I have also tried installing the drivers and kies several times.
I have also tried different PC's to resolve this issue.... still nothing.
The phone charges ok ... so no issues on the charging side.

Make sure usb debugging is on.
Have you tried putting the phone in download mode, starting odin then plugging the phone in and seeing if odin will recognize it? If that works then download the OB7 lollipop stock tar from the general section and flash it with odin.
Hope this helps. Good luck.

I've been through three Note 4's now - ever since Lollipop I cant mount USB in the OS or in recovery. It's absolutely insane. other Sammy phones are fine - I bring them back into the store and they can't mount anything either - so they give me a new phone.
This one came with Lollipop out of the box, so we activate it and plug it into their laptop. It sees the phone and you can see the device in Explorer. I drive home and some apps update on the way.
Get home - NONE OF MY PCs SEE THE ****ING PHONE!!!!
I'l going to have to kill something now - this makes ZERO sense. I know what I'm doing, I know all about drivers, USB debugging, blah blah. Still these Note 4s just plain won't mount USB. They charge fine but PCs don't see them.
I need to root the damn thing so I can get all my apps back on there but of course ODIN can't see a phone that won't mount.
Any advice? Been dealing with this for two weeks now... I can't find anybody else with a similar issue.
